The invention is directed to a waterproofing system comprising a functional layer S1 comprising 10-80 wt.% of at least one thermoplastic polymer P1 and 10-80 wt.% of at least one solid particulate filler F, wherein the surface of the functional layer S1 has an Auto-correlation length of waviness W(Sal) of at least 50 microns. The invention is also directed to a method for producing a waterproofingsystem and to the use of a mechanical surface treatment step to increase the waviness factor, determined as the ratio of the Root mean square roughness of waviness W(Sq) to the square of the Auto-correlation length of waviness W(Sal), of a surface of a functional layer S1. 本发明涉及一种包含功能层S1的防水体系，所述功能层S1包含10-80wt％的至少一种热塑性聚合物P1和10-80wt％的至少一种固体颗粒填料F，其中功能层S1的表面具有至少50μm的波纹度的自相关性长度(Sal)。本发明还涉及一种制备防水体系的方法和机械表面处理步骤用来增加波纹度因子的用途，所述波纹度因子作为功能层S1表面的波纹度的均方根粗糙度W(Sq)与波纹度的自相关性长度的平方W(Sal)的比确定。
